Sciorra, whose credits include The Good Wife and The Hand That Rocks the Cradle, will guest star as Nancy in a case that hits close to home for the Brass family. She'll first appear in the season finale and return for the 14th-season premiere of the CBS procedural.

During the finale, titled "Skin in the Game," the team will investigate the disappearance of Ellie Brass (Teal Redmann), the captain's stepdaughter who was last seen in CSI's sixth season. The episode will explore Brass' troubled marriage and the couple's infidelities.

Tangie Ambrose also will return to play Miss Kitty, who was last seen in Marg Helgenberger's final episode in January 2012.

Repped by APA, Authentic Talent and Literary Management, Sciorra has credits that also include The Sopranos, for which she earned a guest actress Emmy nomination, and True Love, which netted her an Independent Spirit Award nom.
